Description
Non-contact detection: When the electrical test pen detects AC voltage, the screen displays a solid red signal and a beep sounds to alert you. Sensitivity adjustment: You can adjust the sensitivity to high or low using the “S” button. A green backlight indicates low sensitivity, while a yellow backlight indicates high sensitivity. Fire/Live Wire Detection: Insert the pen tip into the socket to detect a live/zero wire. The red backlight will flash, the LCD signal will be solid, and a beep will sound when a live wire is detected. Break Point Detection: As the pen moves with the wire, the audible and visual alarm will stop once the break point is reached. Separation Point Measurement: Safely connect to the electrical system to verify, troubleshoot, maintain, and improve the safety factor of the installation line on-site.
